CHARLES N. BROCK, OF PHILADELPHIA, PENNSYLVANIA.

IM'PROVED SIPHON-FILTER FOR DRAWING SIRUPS, &C.

Specification forming part of Letters Patent No. 39,03, dated June 30, 1863.

.To all whom, it may concern:

Be it known that I, CHARLES N. BROCK, of the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful apparatus, whichl ternia Siplion-I `ilter,lor empty ing the blowup pans used in the manufacture ot` sugar; and I do hereby declare that the following' is a full, clear, and exact description ofthe same, reference being,- had to the accom panying drawing, forming` part of this specitication, said drawing representing` a central vertical section ot' a blow-up pan 7 with the Siphon-filter applied.

The usual mode of emptying' a blowup pan is to melt the sugar in the panand draw the sirup or liquor at or near the bottom through a strainer, thus tirst drawing,` oli' the dirt.

The object of my invention is to draw oi' the sirup or liquor from the surface, where it is clear, and allow the dirt to settle at the bottom ot' the pan, to be shoveled out after the sirup or liquor has been all discharged 5 and to this end it consists in a exible pipe or a pipe with exible or folding joints, with an outlet through the bottom ot' the pan, and with a float and strainer at the top, the float remainingl at the top ofthe sirup or liquor and keeping the strainer just btlow the surface thereof, and the pipe connecting with the strainer in such manner that the sirup or liquor passes through the strainer before entering the pipe.

To enable others skilled in the art to make and use my invention, I will proceed to describe the construction and operation.

A is the pan. B is thepipe, (represented as made ot' metaL) with flexible elbow-joints a aa, its lower part passing through the bottom ot' the pan, and its upper end beingn secured to the strainer G, above the bottom b thereof. D is the float, haring the drawer C attached to its bottom. The whole ot' the strainer is submerged in the sirup or liquor, (tinted red in the drawingY 5) but as it is made very shallow its bottom I), made ot' wire-cloth or other reticulated materiahis kept by the iloat at a short distance from the surface. The pipe B is to be furnished with a stop-cock at a convenient distance below the bottom of the pan', and when the sirup or liquid is to be drawn oft" this stop-cock is opened, and the sirup or liquid passes into the strainer through the bottom b, and thence down the pipe B through the bottom ofthe pan to the outlet. As the sirup or liquid is drawn ott', and the float and strainer desceiul,the pipe B folds up, and when all has been drawn oft' the dirt is removed from the bottom ot" the pan by shovels or other means.

The siphon-tlter is applicable to the emptying' of other vessels than the blow-up pans.

What I claim as my invention, and desire to secure by Letters Patent, is-

Having the filter or filtering-drawer C constructed with the-float D immediatelysabove it,'in combination with thejointed pipe B, all in the manner herein shown and described.
